This isn't an IDL question exactly, but I figured that there are several
here who have to deal with these file types. Is there any real
difference between CDF and HDF? I have looked at some web pages that
describe the differences, but it doesn't mean much to me since I've
never delved into either one. The only reason I'm even looking at these
file types is that these seem to be the types preferred by the data
center we will be working with later on for long-term archival of our
data. If it means anything, my core data sets are nothing more than
really big arrays. Later on, other data like PNG images may be included.
Unless there's some big difference between the two, I'm going to go with
the one that's easier to work with in IDL. So, that brings me to the
question, is one easier to work with than the other? Or do I flip a
coin to determine which one to use?

I just looked at HDF5 documentation for IDL ... it looks like you can't
write HDF5 files in IDL??
Does anyone know of future plans for IDL to support writing HDF5 files?
That may affect your decision on netCDF vs. HDF
